When I buy a new camera one of the first things I do is affix a GGS glass screen protector over the LCD screen. I did this even on my prosumer digital SLR despite its scratch resistant glass screen. The reason why is that while they may be scratch resistant, they also feature anti-reflective coatings that simply do not last the life of the camera. And as that slowly wears away the screen begins to look like it’s lost a battle with sand paper. Not to mention that scratch-resistance does not equate to scratch-proof.
I’m always amazed at how many people buy plastic-film screen protectors (commonly seen on touch sensitive smartphones) that do little if anything to protect the screen. More often than not they occlude the screen as they quickly become scratched. They offer little to no protection from hard objects, and they frequently need replacing (especially given how easy it is to trap air bubbles beneath them).
GGS screen protectors, on the other hand, are different as they are made out of optical quality glass. They are thin, sturdy, and affix tightly to the back of the camera. Once on, they almost appear built into the body (this is where careful application is key). They don’t scratch easily as they are made of glass, and when they do you know you’re investment has been justified.
I’ve personally scratched and shattered a GGS screen protector, and I know without it I would have been left with a potentially ruined screen instead of a cracked $8 investment. The only downside is that when the GGS screens shatter glass shards can fall off despite being laminated. Removal of the broken screen is simple: slide a credit card (or other rigid plastic object) under a side and slowly work your way around until it pops off (if it’s really stuck, warm it with a hair dryer). Depending on how long it’s been in place the adhesive may leave a sticky residue that is easily removed with nail polish remover or a Goo Gone equivalent.
Other brands of glass screen protectors exist, and some even feature anti-reflective coatings that cost 5-10 times more. But none that I have tried are as consistently well reviewed, as minimally invasive, or as affordable as the GGS models. It’s the rare case where the best also happens to be the cheapest.
